PERMAFROST

Eng./Esp.

In geology Permafrost, cryotic soil or permafrost soil, is soil at or below the freezing point of water (0°C or 32°F) for two or more years. The extent of it can vary as the climate changes. Today, a considerable area of the Arctic is covered by Permafrost . https://phys.org/tags/permafrost/

Sunsets started to tease the Arctic horizon as scientists on board the U.S. Coast Guard Cutter Healy headed south in the Chukchi Sea during the final days collecting ocean data for the 2011 ICESCAPE mission. The ICESCAPE mission, or “Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment,” is a NASA shipborne investigation to study how changing conditions in the Arctic affect the ocean’s chemistry and ecosystems. The bulk of the research took place in the Beaufort and Chukchi seas in summer 2010 and 2011.
